It's under POD because that's what I see on the surface?
Not using it but looked into it a few years ago. It's a turnkey art platform to build your own website. I remember being put off because there was a whole involved process of demo and sales pitch. And I couldn't just sign up for a trial to see if it met my needs. Pricing also doesn't seem to be public and after I dug it up it's pretty expensive. Plus they take a transaction fee on your sales.
Again, it's just a website platform. As part of their offering they claim to provide marketing assistance but some of the comments I've seen have been mixed. You only make as many sales as the customers you bring.
This is older info but gives some perspective
